The main objective of prisons is the re-education and social
rehabilitation of offenders, a big task considering that we are trying
to get the social inclusion of persons with complex situations and,
often, of difficult solution. The fi rst objective is reducing negative
consequences of drugs abuse, using programmes to reduce risks and
damage. A second objective is reaching and keeping abstinence periods,
in order to get a dependence cut and a reorganisation of personal
and social dynamics. The social inclusion constitutes the last period
of the changing process, being essential a progressive preparation for
the prison exit, developing activities in order to get the normalization
and social integration. When the moment for the prison exit arrives is
fundamental to continue with the therapeutic process, key element in
order to avoid the relapse in drugs abuse, the personal destabilization
and the offence persistence.
